Nissan Murano: Parking Brake System :: Periodic Maintenance / Parking Brake Shoe
Inspection and Adjustment
INSTALLATION
Adjust parking brake pedal stroke. Refer to Inspection and Adjustment.
Perform parking brake break-in (drag on) operation by driving Nissan Murano vehicle under the following conditions:
-
Drive forward
-
Vehicle speed: Approx. 40 km/h (25 MPH) set (constant and forward)
-
Parking brake operating force: Approx. 140 +49, -0 N (14.3 +5, -0 kg-f, 31.5 +11, -0 lb-f)
-
Time: Approx. 5 +5, -0 seconds.
CAUTION:
To prevent lining from getting too hot, allow a cool off period of approximately 5 minutes after every break-in operation.
After the break-in procedure, check parking pedal stroke of parking brake.
CAUTION:
If it is out of the specification, adjust again. Refer to Inspection and Adjustment.
ADJUSTMENT AFTER INSTALLATION
Adjust the parking brake pedal stroke. Refer to Inspection and Adjustment.
Rotate the disc brake rotor with the parking brake pedal released and check that there is no drag.
CAUTION:
If any drag is found, verify the parking brake components are installed and adjusted correctly.
Inspection and Adjustment
INSPECTIONPedal StrokeOperate the parking brake pedal with a force of 196 N (20.0 kg-f, 44.1 lb-f). Check that the pedal stroke is within the specified number of notches...
